How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
A JSON object with a 'valid' boolean indicating whether the IBAN checksum is correct, plus a 'schema' field identifying the response format as 'delx/util-iban-checksum/v1'.
Example use cases
Pre-transfer IBAN verification
“Before I wire money to this account, check if the IBAN DE89370400440532013000 is valid so I don't send it to the wrong place.”
Customer onboarding bank detail check
“A new customer just entered their IBAN FR7630006000011234567890189 — can you verify it has a correct checksum before we save it to their profile?”
Bulk payment file validation
“I have an IBAN NL91ABNA0417164300 from a supplier invoice — validate it before I approve the payment run.”

Choose this endpoint when you need a lightweight, pay-per-call IBAN checksum check with no signup or subscription required, especially in agent workflows that need to validate IBANs on-demand before initiating international payments. Suitable when cost certainty ($0.001 per call) and verifiable delivery via x402 matter.
Side effects
- Missing or empty IBAN input — likely returns a validation error or bad request
- Malformed IBAN with unsupported country code — may return valid:false or an error
- Payment failure via x402 if USDC funds are insufficient — request is not processed
- Network timeout or service unavailability — no result returned
